The Met Office has issued a yellow weather warning of ice for Ceredigion, Pembrokeshire and Carmarthenshire on Thursday, December 8.

The Met Office reports that Wednesday will be frosty start, but mainly dry with plenty of sunshine. Scattered showers may affect coastal Pembrokeshire and for all it will feel cold with a gentle northerly breeze, and a maximum temperature of 5°C.

There is a risk of showers on Thursday, which could turn wintry at times, becoming even colder with sharp overnight frosts.

Some disruption is likely due to icy surfaces, including injuries from slips and falls on icy surfaces. There could be icy patches on some untreated roads, pavements and cycle paths.

A Met Office spokesperson said: "Some roads and railways may be affected with longer journey times by road, bus and train services.”

 

Met Office Deputy Chief Meteorologist, Rebekah Sherwin, said: “As the cold air pushes across the UK from the north temperatures will dip, with daytime temperatures struggling to get above freezing in many places from mid-week onwards.

"However, the cold air from the Arctic will also bring brighter conditions, with some dry, sunny spells, particularly away from the coast.

“Showers will turn more wintry as the week goes on with a risk of snow at times. Yellow warnings for ice and snow have been issued for parts of Scotland, Northern Ireland, Wales and the east coast of the UK for Wednesday and Thursday.

"We can expect to see further snow and wintry showers as the week progresses, particularly in coastal areas or over higher ground. There will be widespread frosts with temperatures falling to as low as -10°C overnight in isolated spots by the end of the week."

RAC spokesman Rod Dennis said: “With temperatures plummeting this week, many drivers might be taken aback by the cold after an exceptionally mild autumn.

"Our advice is to be winter ready – check tyres are properly inflated and with good tread, while topping up oil, coolant and screen wash levels if needed.

"Drivers with older batteries in their cars might also wish to give their vehicle a 20-minute drive before colder conditions arrive to ensure the battery can cope with sub-zero temperatures.

"It’s also worth having a fully-charged mobile phone and carrying a blanket in case of a breakdown to keep warm.”

Although there are some uncertainties around how long this cold spell will last it is expected to stay cold into next week, with temperatures remaining well below average for the time of year.
